Hi devs,
I don't understand one thing:
I have table:
CartItemTable = sql.Table(
"CartItem", meta.metadata,
# Relations
sql.Column("userId" , sql.Integer ,
sql.ForeignKey("User.userId"), nullable=False, primary_key=True),
sql.Column("productId" , sql.Integer ,
sql.ForeignKey("Product.productId"), nullable=False,
primary_key=True),
sql.Column("variantId" , sql.Integer , nullable=True,
default=None),
# Count of items in shopping cart
sql.Column("count" , sql.Integer ,
nullable=False, default=1)
)
and I want to insert multiple rows to it using sql:
Session().execute(
CartItemTable.insert(),
[{
CartItemTable.c.userId : self.user.userId,
CartItemTable.c.productId : item.product.productId,
CartItemTable.c.variantId : vid(item.variant),
CartItemTable.c.count : item.count
} for item in self.items]
)
But this not works and I must use this way:
Session().execute(
CartItemTable.insert(),
[{
"userId" : self.user.userId,
"productId" : item.product.productId,
"variantId" : vid(item.variant),
"count" : item.count
} for item in self.items]
)
Why is not working first syntax, what em I missing ?
Cheers
